7-(Chlorodifluoromethyl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-5-(4-(trifluoromethyl)phenyl)pyrazolo[1,5-a]pyrimidine (CAS 439097-22-0) is a high-purity analytical reference standard with the molecular formula C24H16ClF5N4S and a molecular weight of 522.92 g/mol.
7-(Chlorodifluoromethyl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-5-(4-(trifluoromethyl)phenyl)pyrazolo[1,5-a]pyrimidine (C24H16ClF5N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
